The $75 ones are long gone. People that have these, know the value of owning the last few available and are cashing in. Yes, Marco is nuts to ask the price they want. Here is the next best thing.

Be aware that shipping from them is veeeeeery slow and communication is poor, but you will eventually get one.
I drilled both holes in my ramp to mount it in the same place as on the Premium. If you look at pics online, you can kind of see where the holes are in the premium ramp. Then look at where the train was originally mounted. Mark the ramp with tape near the edges of the train when you get it where you want. Then, pull the ramp out, hold the train next to your tape and mark the holes in the ramp, with a scribe, from the bottom side. The rear screw just screws into the train. The front screw needs to have a nylock nut fished up inside the train.
I wired my train light to the Jam Multiball insert. Keep in mind, you have to wire a diode in series with the light. This way, it lights when you have made enough train ramp shots for Jam Multiball to be available.
